Description
Technical field
The invention belongs to artificial leather manufacturing fields, and in particular to a kind of low smell polyurethane leather and preparation method thereof.
Background technique
With China's rapid development of economy, the demand of leather and fur products is increasing, and class is also higher and higher.In automobile
Dressing leather has been widely used in the inside gadget of riding vehicle, carrier.Leather for automobile interiors, optimal selection are corium, but
It is serious that corium pollutes environment in its own production process, and content of beary metal is easy exceeded, becomes a useful person in inside gadget process
Rate is lower, and it is expensive, it is difficult to be received by low and middle-grade passenger cars；And people gradually pay attention to environmental protection, are advocating
Today of environmental protection and energy saving, sustainable development, people also start to develop leather fabric to replace animal's leather, to avoid to wild
The injury of animal and destruction to natural environment.
Rtificial leather is also imitation leather or rubber, is the general name of the artificial materials such as PVC and PU.It is in woven fabric base or nonwoven
On Bu Ji, formed by the foaming such as the PVC and PU of various different formulations or overlay film processing and fabricating, it can be according to varying strength, wear-resisting
Degree, the requirements such as degree and color, gloss, floral designs of resisting cold are processed into, with designs and varieties are various, waterproof performance is good, not care about one's appearance
Neatly, the feature that utilization rate is high and price is cheap with respect to corium.Vapour is currently, automobile door plate, face fabric for automobile seat, instrument board, vehicle
The positions such as compartment inner wall, Roof of vehicle, steering wheel cover, mainly using materials compound with polyvinyl chloride, polyurethane etc. such as non-woven cloths
Material.Common polyvinyl chloride rtificial leather is there are Boardy Feeling, comfort is poor, loss of properties on aging, smell weight, plasticizer are easy to migrate
The defects of precipitation, so the common PVC artificial leather in automobile interior decoration is gradually replaced polyurethane (PU) synthetic leather at present.
And existing Synthetic Leather production technology is complex at present, the Shortcomings such as wearability, flexibility, feature of environmental protection.
This field needs to develop a kind of polyurethane leather, and performance can match in excellence or beauty with PU polyurethane, but has low
VOC and the feature of environmental protection.
